Polymer Modified Bitumen: Review

open access: yesChemistry & Chemical Technology, 2016
The main reasons and ways of bitumen modification by polymers were examined. Positive and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic elastomers, reactive polymers, thermoplastics) were analysed. The authors’ achievements concerning modification of bitumen by various polymers, namely indene-coumarone ...

Rheological characterisation of bituminous binder blends for the design of asphalt mixes containing high recycled asphalt content

open access: yesActa Technica Jaurinensis, 2023
Reclaimed asphalt pavement (RAP) is gained from road reconstructions; however, its usage is less optimised in Hungary and neighbouring regions, since on the project level the proportion of RAP in the asphalt mixes is only 10-15%.

Valorization of phosphogypsum waste as asphaltic bitumen modifier [PDF]

open access: yesJournal of Hazardous Materials, 2014
The accumulation of phosphogypsum waste from the fertilizer industries, which remain in regulated stacks occupying considerable land resources, is causing significant environment problems worldwide. In that sense, the scientific community is being pressured to find alternative ways for their disposal.
